I go with this simple formula, which may not be exactly right but it's close I think, and good for comparing one size to another.
26" = 559mm 650B = 584mm 700c = 622mm Tire outside diameter = rim diameter + (2 x tire diameter) ie 650b x 42 would be 584 + 42 + 42 = 668mm -> your radius is therefore half that, 334mm I think this is accurate enough for whomever's asking, but if you have the bike with the wheels and you can just measure, just measure ground to the top of the tire and divide by two On Wednesday, 15 July 2020 at 16:21:55 UTC-7 Joel Stern wrote: > I was asked to get my tire radius and I have no cluehow to do it. > > I am riding the 42mm Baby Shoe Pass > > I have them on a Velocity Synergy rim, this are the specs.
